    摘要: The invention relates to a process for producing water-soluble or water-swellable polymer products with low levels of residual monomers using acrylic acid and/or acrylic acid derivatives, which process is characterized by adding a nitrogen compound to the monomer solution to be polymerized and subsequent heating of the polymer product at temperatures of from 120 to 240° C. The polymers produced accordingly are suitable for use as flocculants, dispersants and absorbents.

    摘要: The invention relates to a process for the preparation of .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, novel .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, a process for the polymerization of these novel .alpha., .beta.-unsaturated N-substituted carboxylic acid amides, including the polymers, and the use of these polymers as sedimentation, flocculating, dewatering and retention aids, as additives for mineral oils, and as ion exchangers.The .alpha., .beta.-unsaturated N-substituted carboxylic acid amides are prepared by transamidation of .beta.-hydroxy or .beta.-alkoxy carboxylic acid amides with primary amines and heating of the N-substituted .beta.-hydroxy or .beta.-alkoxy carboxylic acid amides obtained as intermediate products in the vapor phase in the presence of catalysts. Primary amines are preferably used in the conversion which have no hydrogen beta to the amino group.These .alpha.,.beta.-unsaturated carboxylic acid amides may be neutralized and/or quaternized and polymerized by processes which as such are known alone or with other comonomers, and preferably acrylic or methacrylic acid derivatives such as acrylamide, to give cationic polymers. These polymers are suited for use as flocculating and sedimentation aids, as dewatering and retention aids in papermaking, as additives for mineral oils, and as ion exchangers.
